1 Claim. (Cl. 16--159) This invention relates to what is commonly referred to as knockdown wardrobes, cabinets and the like employing detachably coupled wall sections with doors or closures hingedly mounted on a door-frame portion of the wardrobe or cabinet. More particularly, the invention deals with a drive hinge construction for mounting the doors on the door-frame. Still more particularly, the invention deals with a door construction having transparent panels rendering the interior of the wardrobe or cabinet visible.

Thenovel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a perspective view of a cabinet made according to my invention.

Fig. 2 is an enlarged section on the line 22 of Fig. 1 showing only part of the construction.

Fig. 3 is a section on the line 3-3 of Fig.. l on an enlarged scale.

Fig. 4 is a perspective view of one of the hinges which I employ; and

Fig. 5 is a section on the line 5-5 of Fig. 3.

In the construction of cabinets of the kind under consideration, an extreme difliculty has been experienced from a production standpoint in the mounting of hinge members on the door and door-frame to insure proper alinement and fitting and one of the objects of my invention is to provide a drive hinge construction, by means of which the assemblage or mounting of the doors in the door-frame is materially expedited, thus insuring better results and materially cutting down on the cost of production of the complete device.

Further, it is an object of the invention to provide doors having transparent panel portions rendering the interior of the resulting wardrobe or cabinet visible, so that access to particular garments hung in the wardrobe or cabinet is visible, thus controlling the particular door which is opened for the purpose of removal of the selected garment.

In Fig. 1 of the drawing, I have shown a knockdown cabinet comprising four primary parts or sections, namely a back and side wall section 10, a top section 11, a bottom section 12, including a front panel portion 13 and a doorframe section or unit 14.

Devices of the kind under consideration are wellknown in the art and, from this standpoint, a brief description of the various sections of the cabinet will be given. The top section has depending walls at the back and side thereof, one of which is seen at 15 and the side walls have reinforcing edge strips, as at 16. The front of the top wall has a forwardly projecting flange portion 17 which fits in a groove 18 of a top rail 19 of the door-frame 14. The bottom wall section 12 has upwardly extending side and back flanges, one side flange of which is indicated at 20, and the front wall portion ice 13 has rearwardly extending side flanges, one of which is seen at 21. All of the flange portions 15, 20 and 21 are secured to the walls of the section 10 by suitable fasteners as indicated at 22.

The front wall portion 13 of the section 12 has an upwardly extending flange portion 23 fitting in a groove 24 of the lower rail 25 of the door frame 14. The door frame 14 has grooved side rails 26-for reception of the forward edges of the side walls of the section 10. The frame 14' also includes a vertical center post 27, with which is pivotally coupled door-retaining members 28.

At 29 and 29 are shown two doors, each being of similar construction and comprising elongated rectangular frames. These doors are mounted in the frame section 14 byhinges 30 and, as all of these-hinge constructions and mountings are the same, the brief description of one, will apply to all.

Within the cabinet is a garment hanger rod 31 supported on cleats or strips 32 on inner surfaces of side Walls of the section 10.

Considering now Fig. 3 of the drawing, in which a section through one of the side rails 33 of the door 29 is shown, this rail has a grooved outer edge, as at 34, to receive the frame 14 and provide an overlapping flange portion 35 on the outer surface of the frame. This flange portion limits closing movement of the door and a similar portion is provided on the rail of the door which engages the post 27. The inner edge of the rail 33, as well as other rails of the door 29 has a groove, as at 36, for the reception of a transparent sheet 37 of suitable plastic material which sheet is held in position by a series of strips 38 which may have simply a drive fit or may be adhesively or otherwise secured into position.

In Fig. 3 of the drawing, a section through one of the hinges 30 is shown and one of these hinges is shown detached in perspective in Fig. 4 of the drawing. Each hinge comprises two butts 39 and 40, the butts having interengaging pintle bearings, as at 41 and 42, respectively, joined by a pintle pin 43.

Outer peripheral edge portions of the butt 39 have short depending flanges, as at 44, the flanges extending into an outwardly rounded portion 45 centrally of the outer edge of the butt. At each side of the rounded portion 45, the flanges 44 are extended to form pairs of prongs 46.

Each prong has a substantially triangular-shaped prong end 47. These prong ends have recessed sides, as at 48, which form barbs 49. Note the dotted line showing in Fig. 5.

It will also appear that the extending metal forming the prongs is split, as seen at 50, to such an extent that, in driving the prongs into the door 29 or the rail 33 thereof, as seen in Fig. 5, the pairs of prong ends 47 flare outwardly substantially in the manner indicated. In other words, the split opens up and the barbs 49 extend into the rail 33, thus permanently retaining the butt 39 on the rail 33.

The butt 40 has two similar pairs of prongs 46 which have prong ends 47, similar to 47, with barbs, as at 49', so that, when the butt 40 is driven into the doorframe section 14, the prong ends 47' will spread securely anchoring the butt in position. The butt 40 has a relatively deep plate portion 40' forming a stop edge 51 between the pairs of prongs which limits inward movement of the butt 40 and this plate portion 40 compensates for the thickness of the flange portion 35 on the door 29, as will clearly appear from a consideration of Fig. 3 of the drawing.

Considering Fig. 2 of the drawing, it will appear that the lower rail 52 of the door 29 is of a width corresponding to the width of the lower rail 25 of the door frame 14, so that outer surfaces of the doors 29, 29 will be flush with the rail 25, as well as the rail 19.

doors 29, 29" can be properly fitted in the door-frame section 14 and then the respective hinges- -30 driven into position to enterthe door-frame section 14 and the doors thus insuring proper fitting and hinge mounting of the doors. It will be apparent that this operation is accomplished in a very simple and economical manner. It will be understood that the transparent panels of the doors will facilitate selection of the clothes.

' Having fully described my invention, what I claim as newand desire to secure by Letters Patent is:

A drive hinge of the character described, comprising apair of hingedly coupled butt plates, said platesbeing substantially of the same length: and having end edges in common alinement, one butt plate having two pairs of prongs disposed in the plane of the plate and projecting therefrom,- said butt platehaving a stop edge between said prongs and spaced from the hinge axis of said butt plate, the other butt plate being arranged at right angles to the first named butt plate in the closed position of the hinge and having two pairs of prongs disposed at right angles to said second butt plate and parallelling the prongs of the first butt plate in the closed position. of the hinge, each pair of prongs having outwardly extending. barbs disposed Within the greatest width of the base of the prongs, arrangement of said prongs in closed position of the hinge facilitating simultaneous drive attachment of both butts into two supports, said stop edge checking movement of the first butt plate into its support, the prongs in each pair having normally abutting edges and diverging edges, and the diverging edges of the prongs in each pair operating to spread the prongs laterally in said drive attachment to supports to extend the barbs to a point beyond the normal width of the base of the prongs in engaging the supports to retain the hinge against displacement therefrom.
